Graphite: group by node fragment

If I have metrics named:

statsite.gauges.a-ABC-1.thing
statsite.gauges.a-ABC-2.thing
statsite.gauges.a-CBA-1.thing

Is it possible to group these metrics by a particular fragment, for instance:

statsite.gauges.a-{groupByThisPart}-*.thing

So that I can feed them into another function such as sumSeries.

Solution

  • This is possible by using aliasSub to convert the '-' into '.', as follows, apply:

    aliasByNode(seriesName, 2)

    which outputs 'a-CBA-1'. Then apply:

    aliasSub(seriesName, \d{4})-(\d{4})-(\w{5}, \1.\2.\3)

    which outputs 'a.CBA.1'.

    Then you can use groupByNode to sum all the parts for the 2nd fragment.

    groupByNode(seriesName, 1, sum)
